Solution
The correct option is C leg-haemoglobin
Leguminous haemoglobin (leg-haemoglobin) is a pink pigment present in the root nodules of leguminous plants and is essential for nitrogen fixation. The enzyme nitrogenase is sensitive to oxygen and requires anaerobic conditions. Leg-haemoglobin acts as an oxygen scavenger and helps in oxygen removal and thus provides anaerobic conditions for the enzyme to work.
Nitrate reductase catalyzes the reduction of nitrate to nitrite.
Hydrogenase recycles the H2 produced in N2 fixation.
Plastocyanin is a copper containing protein involved in photosynthesis during the electron transport process.
